Question
Which of the following class of antibiotics are manufactured exclusively by chemical synthesis?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Quinolones (e.g., ciprofloxacin) are a class of synthetic broad-spectrum antibiotics, meaning they are entirely produced through chemical synthesis rather than being derived from natural microbial products.
Hint
Most antibiotics have natural origins, but some important classes are purely man-made.
